摘要：

This research investigates the effects of various HIP conditions on bifilms and mechanical properties of aluminum castings. A206 castings were non-HIPed or HIPed at (i) temperature typical for RLP, (ii) at solution heat-treat and (iii) at eutectic melting temperatures. Average and threshold tensile and fatigue properties improved as a result of HIP although elongation and fatigue life variability did not decrease. We propose that this is due to HIP's ability to heal porosity and thin bifilms more effectively than thicker bifilms.
