This has important implications for the design of metallic glass matrix composites. A ductile particle reinforcement phase blocks the propagation of shear bands and distributes plastic deformation over a larger volume, giving rise to extensive stable crack growth at stress intensities double the intrinsic toughness of the unreinforced bulk metallic glass.

The plastic deformation of bulk metallic glasses (BMGs) depends significantly on applied stress states, and more importantly, in practical applications of BMGs as structural materials, they always deform under complex stress fields. The understanding of deformation behavior of BMGs under complex stress fields is important not only for uncovering the plastic deformation mechanisms of .

Recently, a lowcost nearβ titanium alloy (Timetal LCB wt %) containing iron and molybdenum has been developed. This alloy is cold formable in the β microstructure and can be aged to high strengths by precipitating the a phase. Due to its combination of cold formability and high strength, the alloy is a potential replacement for steel components in the automotive industry.
