| Abstract: | Six kinds of beryllium powders with different particle sizes (4 ～ 15 μm) and low oxygen prepared by impactgrinding were compacted and consolidated by cold-hot isostatic pressing (CIP-HIP). The tensile strength, yield strength,elongation and micro-yield strength(MYS) of the materials were tested and it showed that the strength of the materials,especially the yield strength and micro yield strength(MYS) increase obviously with the refinement of grain size. From theXRD and TEM, the second phase is BeO which is finely dispersed in matrix. This is considered to be the main strength-ening mechanism for CIP-HIPed beryllium materials with higher purity |
