Effect of Secondary Hot Pressing on Microstructure and Mechanical Properties of Be-Al Alloy Prepared by Powder Metallurgy AITranslate
Abstract AITranslate
The effect of secondary hot pressing process on the microstructure and mechanical properties of Be-Al alloy prepared by powder metallurgy was studied,and the fracture morphology of the alloy was analyzed.The results show that in primary hot-pressed Be-Al alloy,nearly spherical beryllium particles is distributed in continuous aluminium matrix,and the alloy has tensile strength of 230 MPa,yield strength of 157 MPa and elongation of 3.5%.In secondary hot-pressed Be-Al alloy,the boundary of beryllium phase is rough,aluminum phase has grain boundaries with nearly round grains,and the alloy has increased tensile strength of 304 MPa,yield strength of 253 MPa and elongation rate of 1.5%.The fracture of primary hot-pressed Be-Al alloy has no obvious crack source,and shows uniform plastic deformation mainly with transcrystalline cleavage fracture of beryllium phase and ductile fracture of aluminum phase.The fracture of secondary hot-pressed Be-Al alloy has obvious crack source.In addition to plastic deformation fracture of the aluminum phase and a small amount of cleavage fracture of the beryllium phase,the fracture of beryllium aluminum phase boundary occurs in secondary hot-pressed Be-Al alloy.
