The choice of foaming agent and its mass fraction significantly affect the size number metal foam cells. powder metallurgy process was used to produce aluminium foams with addition various agents: titanium hydride (TiH2) calcium carbonate (CaCO3). TiH2 added in an amount 0.4 wt.%, while quantity CaCO3 varied between 3 5 wt.%. produced foams, approximately same degree porosity, were scanned usin...

The structure changes, microstructure evolution, and mechanical properties during Powder Metallurgy (PM) through High Vacuum Sintering of a Ti-TiH2 matrix reinforced with Titanium Diboride (TiB2) particles were investigated. Composites fabricated at 850, 1100, 1300 °C. strategy for the fabrication process was to use PM route employing titanium hydride (TiH2) reduce consumption Commercially Pure...

Unsaturated titanium hydride (TiHX) powder has high formability and is a promising raw material for titanium-based metallurgy. In this work, TiH2, TiHX, HDH Ti powders were characterized, the cold compaction behavior of was investigated, densification mechanism analyzed. The TiHX three-phase mixture containing an α plastic phase δ ε brittle phases through Rietveld refinement. compacts had compr...

The reaction betw een catalytically prepared m agnesium hydride (M gH 2*) and [TiCl3(T H F )3] in a molar ratio o f 1.5:1 in T H F yields a highly pyrophoric, X-ray am orphous titanium hydride precipitate with the com position [TiH2 -(M gC l2 -2 T H F )0.2-o.3] (2). This novel titanium hydride has been characterized through hydrolysis and iodolysis, as well as through therm olysis to Ti* and H ...

Using TiH2 powder, Al-V alloy powder and V as raw materials, Ti-3Al-2.5V was prepared by ordinary pressing vacuum sintering, the structure mechanical properties of were studied. The results show that metallurgy is a near-α type alloy, with relative density about 98%. data tensile strength, yield strength elongation are more prominent, key performance reaches forged Ti -3Al-2.5V level.
