Of Pb-free solder choices, an array of solder alloys based on the Sn-Ag-Cu (SAC) ternary eutectic (Teut = 217°C) composition have emerged with potential for broad use, including ball grid array (BGA) joints that cool slowly. This work investigated m

Studies of bulk AlMgB 14 and TiB 2 composites have shown that these materials exhibit exceptional resistance to erosive and abrasive wear. Multi-hour ASTM erosion tests with Al 2 O 3 abrasive against composite samples comprised of AlMgB 14 (40 vol.%)
