Abstract
The Hot Isostatic Pressing process on a commercial basis has been applied only to high cost castings (aerospace and racing). Porosity elimination is the application purpose, saving a casting from unacceptable levels of porosity. H.I.P. is very expensive. Manufacturing cost of aerospace and racing castings is very high so H.I.P. is accepted because economically convenient.
This paper reviews and discusses: 1) The development of an innovative Hot Isostatic Pressing process named Liquid Hot Isostatic Pressing with the goal to overcame the cost issue of gas H.I.P., 2) L.H.I.P. effect on Mechanical Properties of Treated Specimens vs. not treated and Comparison of Treated Castings vs. not treated, 3) Range of Components this process can be applied to.
The potential of high strength, very light and cost effective aluminum casting production can be achieved by utilization of the L.H.I.P. process.
