Processing, micro structure and mechanical properties of W_(50)Al_(50) bulk alloy obtained by mechanical alloying and hot-pressing

摘要

The Al_(50)W_(50) alloy bulk bodies were fabricated by using mechanical alloying and hot-pressing in this work. The Al_(50)W_(50) alloy had excellent thermal stability up to 1300 deg C under vacuum and Its optimum microhardness, bending strength and compressive strength were 10.21 GPa, 570 MPa and 2.07 GPa, respectively.
