    摘要： A method of heat treating high pressure die cast objects using pressure is disclosed. A high pressure die cast object is obtained and solution heat treated to above 700° F. for at least 2 hours at pressures between 0.5 and 35 KSI or at any pressure or range of pressures therebetween. This method of solution heat treatment with pressure reduces and/or eliminates blistered defects on the high pressure die cast object. The method of heat treating by solution heat treatment with pressure also allows an increase of yield strength and corresponding weight reduction upon redesign or substantially larger safety factors for the cast object.

    摘要： An improved shot sleeve for high pressure die casting of low-iron Aluminum Silicon alloys and a method of making the shot sleeve, the shot sleeve includes a top portion including a pouring hole and a bottom portion including an impingement site on an inner surface of the bottom portion opposite the pouring hole. The impingement site is constructed of an erosion resistant material. The erosion resistant material is selected from: titanium, tungsten, molybdenum, ruthenium, tantalum, niobium, chromium, vanadium, zirconiwn, hafnium or a secondary, tertiary or quaternary alloy formed from combination thereof. An erosion resistant insert located at an impingement site of a shot sleeve may accomplish the construction. The insert may be introduced into an internal surface of a conventional shot sleeve or replace a bottom portion of a conventional shot sleeve.
