Abstract
Wear of steel at high temperature is a complex phenomenon. Quantification of wear per event is an important aspect in assessing life of a component. Necessity of economics and light weighted components compels to study the system under common parameters and extrapolate the results. Temperatures/pressures inside a gun are impossible to be measured by direct methods. Mathematical modeling and comparison of results with end effect measurable parameters is only way to predict it's accuracy. There is no one such quantitative demonstration which can predict accurate wear rate. Gun wear is unique to gun system and no one theory fits into predictions of gun wear. Gun wear is unique phenomena wrt any particular gun system and needs to be studied independently. Numerous studies have been carried to study steel wear below 600°C. Wear studies at higher temperature i.e. above 600°C is not enough to describe correct wear phenomena.

Summary
Wear of steel at high temperature is a complex phenomenon. Quantification of wear per event is an important aspect in assessing life of a component. Assessing wear rate of steel is an important study for design engineer for design of optimum gun system. Formulas derived by Jones[6] were modified by Shulyer[6] and Kent[7] stated that gun wear is independent of shot mass. Izak M Synmam[11] simulated gun wear assigning it to be caused by temperature and heat transfer alone as proposed by Thornhill[8].
