Kulkarni, V.R.Nayak, J.Dabhade, V.V.2026-02-062018International Journal of Modern Physics B, 2018, Vol.32, 19, p. -2179792https://doi.org/10.1142/S0217979218400404https://idr.nitk.ac.in/handle/123456789/31350The present work deals with sinter-forged powder metallurgical (P/M) steels alloyed with chromium by addition of ferrochrome powder, which allows a close control over the chromium contents of alloy steels. Chromium contents can be varied by adjusting appropriately weighed ferrochrome powder in the P/M mixtures. Fe-Cu (2%) and C (0.7%) is the base composition for this P/M alloy steel. Study with the addition of 0.5% and 3% chromium by weight in the form of ferrochrome powder is carried out. The P/M alloy steel of base composition with no chromium content is also prepared for comparative study. The paper deals with these three alloy steels formed by the sinter-forging technique of powder metallurgy. The results of hardness and wear in hardened and tempered condition are reported in the present work. © 2018 World Scientific Publishing Company.ferrochrome powderPowder metallurgysinter-forgingsintered alloy steels
