Abstract: The present disclosure relates to a preparation process of a Ti3AlC2 ceramic phase-toughened molybdenum alloy. The preparation process includes: mixing MoO2 and Ti3AlC2 powders, sieving to obtain a mixed powder, and then conducting high-temperature hydrogen reduction; mixing a resulting reduced powder with a coarse-grained Mo powder to obtain a precursor powder; putting the precursor powder into a cladding material to allow hot-pressed sintering; subjecting an obtained sintered molybdenum alloy to high-temperature treatment and thermoplastic processing in sequence; and annealing an obtained processed molybdenum alloy to obtain a high-strength and high-toughness molybdenum alloy. In the present disclosure, a Ti3AlC2-containing ultrafine powder prepared by reduction is mixed with the commercial coarse-grained molybdenum powder in a certain proportion to obtain the precursor powder. After the precursor powder is subjected to the hot-pressed sintering, the molybdenum alloy can achieve a higher density and finer grains.

Abstract: A Ni-based superalloy composition to be used for powder-based additive manufacturing (AM) technology, such as selective laser melting (SLM) or electron beam melting (EBM). The cracking susceptibility during an AM process is considerably reduced by controlling the amount of elements, especially Hf, that form low-melting eutectics.

Abstract: Some variations provide a metal matrix nanocomposite composition comprising metal-containing microparticles and nanoparticles, wherein the nanoparticles are chemically and/or physically disposed on surfaces of the microparticles, and wherein the nanoparticles are consolidated in a three-dimensional architecture throughout the composition. The composition may serve as an ingot for producing a metal matrix nanocomposite. Other variations provide a functionally graded metal matrix nanocomposite comprising a metal-matrix phase and a reinforcement phase containing nanoparticles, wherein the nanocomposite contains a gradient in concentration of the nanoparticles. This nanocomposite may be or be converted into a master alloy. Other variations provide methods of making a metal matrix nanocomposite, methods of making a functionally graded metal matrix nanocomposite, and methods of making a master alloy metal matrix nanocomposite. The metal matrix nanocomposite may have a cast microstructure. The methods disclosed enable various loadings of nanoparticles in metal matrix nanocomposites with a wide variety of compositions.
