Q1. What contributions have the authors mentioned in the paper "Wear analysis of hot forging dies a thesis submitted to the graduate school of natural and applied sciences of the middle east technical university by siamak abachi in partial fulfillment of the requirements for the degree of master of science in the department of mechanical engineering" ?

In this paper, a finite volume analysis of a closed die hot forging and wear measurement of the worn die is presented. 

Q2. What are the future works in "Wear analysis of hot forging dies a thesis submitted to the graduate school of natural and applied sciences of the middle east technical university by siamak abachi in partial fulfillment of the requirements for the degree of master of science in the department of mechanical engineering" ?

The following future studies can be suggested: - This method can be applied for other metal forming process like warm forging or cold forging to obtain new values of wear coefficients. - Effects of contact pressure, sliding velocity and temperature can be studied on wear coefficient. The study can be extended for forgings with different geometries. - A database can be prepared by study on the different die and forging materials.
