Preface

Natural glasses are formed in various materials, for example, oxides and polymers, while commercial metallic alloys have a crystalline structure either after slow or rapid cooling on casting. Metallic glassy alloys were first produced by using sputtering and rapid solidification techniques at very high cooling rates. Many amorphous alloys produced until the last decade of the last century, being marginal glass-formers, have been obtained in the shape of melt-spun ribbons or thin films. Later rod-shaped samples over 1 cm in diameter (called bulk metallic glasses, BMG) were produced by casting of the alloys, having high glass-forming ability in a variety of alloy systems including Rare-Earth (RE) metals-, Mg-, Zr-, Ti-, Fe-, Co-, Pd-, Pt-, Au-, Ag-, Cu-, Ni-, and Ca-based system alloys. These amorphous/glassy alloys demonstrate high strength, good elasticity, high wear, and corrosion resistance. The existing data on the glass-forming ability (including chemical compositions, critical size of fully glassy/amorphous sample, their characteristic temperatures, etc.) as well as physical and chemical properties of metallic amorphous materials have been collected since the database project AMOR was started in 1993 and are presented in the database. The first volume of this series, LB III/37A, presenting 6,450 compositions from 351 ternary amorphous alloy systems of fully amorphous, mixtures of amorphous and crystalline as well as crystalline and quasi-crystalline phases in the form of composition triangles and tables, was published in 1996. The second volume, LB III/37B, a successor volume to LB III/37A, accumulating the data on the structural, thermal, mechanical, magnetic, electrical, and optical properties as well as the corrosion behavior of the ternary alloys listed in volume A, was published in 2011. In addition, another 32 ternary amorphous alloy systems found in the period from 1995 to 2008 were added to volume B updating important information on ternary amorphous alloys. The third volume, LB III/37C, focuses on quaternary metallic amorphous alloys, which are of great interest for industrial applications. The volume covers the general physical structure, as well as thermal, mechanical, magnetic, electrical, and optical properties. The current fourth volume presents the data of five-component metallic amorphous alloys, including a large number of specimen obtained by adding a fifth component to a quaternary alloy; some were obtained by starting from lower v

component base alloys, and there are a few examples of so-called high-entropy alloys. Structural data include diffraction profiles, radial distribution functions, coordination numbers, interatomic distances, etc. The methods include X-ray diffraction, small-angle x-ray scattering, small-angle neutron scattering, atom probe field ion microscopy, electron probe micro analysis, EDX, EXAFS, and XANES Spectra as well as X-ray photoelectron spectroscopy. Thermal properties include specific heat capacity, Debye temperature, atomic diffusivity, thermal expansion coefficient, glass transition temperature, reduced glass transition temperature, crystallization temperature, enthalpy of crystallization, structural relaxation, supercooled liquid range, melting enthalpy, critical quantities for formation of amorphous phase, and configuration entropy.

This is the fourth volume on metallic glasses in a series, the second one related to ternary and the third one to quaternary metallic glasses, which presents information on various properties of multicomponent bulk metallic glasses. Besides amorphous materials obtained by thin film deposition techniques [54BUCK01], the first metallic glass [15GREE02], namely Au-Si alloy, was produced by rapid solidification of the melt in 1960 [60KLEM03]. In the 1970s, noble metals-based bulk metallic glasses of 1–2 mm diameter were also produced [74CHEN04]. For a long time period, Pd-CuSi and Pd-Ni-P were known to be the best metallic glass formers, but remained a laboratory curiosity at that time. In the 1980s, Pd-Ni-P bulk metallic glass having a critical size of 10 mm was produced by fluxing and water cooling [82KUI05]. A large number of bulk metallic glasses defined as 3D massive glassy articles with a size of not less than 1 mm (by another definition not less than 10 mm) in every spatial dimension have been produced so far in the thickness range of 100–102 mm after several pioneering works made in the late 1980s to the beginning of the 1990s [95INOU06, 99JOHN07]. Non-noble-metal-based metallic glasses were initially made in Mg-, La-, and Zr-based alloys (Fig. 1) and later in various other systems [10SURY08].

Introduction

Although a few binary bulk metallic glass-forming systems are known, the composition ranges are narrow and the glass-forming ability of the samples is limited while the addition of a suitable third, fourth, and fifth element drastically improves the glass-forming ability (Fig. 2) [10LOUZ09].

Although bulk glassy alloys are much larger in size than ribbon samples on casting, they are still cooled at high rates of about 102–103 K/s (Fig. 3a) [10LOUZ10]. Thus, the samples are produced under highly nonequilibrium conditions compared to conventional metallic alloys cast as large-size ingots of decimeters and even meters in size. 10000

Upon homogeneous crystal nucleation from the melt on cooling, intrinsic parameters indicating high glass-forming ability of metallic glasses are the reduced glass transition temperature, liquid fragility, and many others [08LOUZ11]. ΔTx and γ can be considered only as nearly intrinsic, since Tx is dependent on the heterogeneous

nucleation. The extrinsic factors influencing the glass-forming ability are as follows [08LOUZ11]: the factors that modify the melt-mould heat transfer coefficient such as mould surface quality and cleanliness, mould surface temperature, thermal conductivity of the mould, casting temperature, casting pressure, liquid metal turbulence during casting as well as upon chamber pressure [04KATO12], and the atmosphere. These factors which are difficult to control experimentally play a central role in the poor reproducibility in the critical thickness for a given metallic glass composition. The second group of factors takes into account heterogeneous nucleation. Possible sources of heterogeneous nucleation include irregularities of the mould and melt cleanliness, existence of impurities, or inclusions which cause heterogeneous nucleation of crystals [06WILD13]. Bulk metallic glasses possess (Fig. 4) unique physical (absence of grain boundaries), mechanical (high strength, hardness, and elasticity wear resistance), chemical (high corrosion resistance), and good soft magnetic (low coercive force and high permeability) properties. 6 Co
