“…Experimental verification of the H-P-type prediction in equation (4.2) was demonstrated for a compilation of iron and steel measurements [65,[73][74][75][76][77]. The large plastic zone sizes associated with the measurements were found to be relatively independent of the material grain size.…”

“…Terdapat beberapa studi melakukan penelitian tentang efek dari parameter proses Carburizing, seperti temperatur quenching, waktu tahan (holding time), temperatur tempering, dan waktu pendinginan yang menggunakan media pendingin oli [10][11][12][13][14]. Proses Pack Carburizing merupakan proses pengerasan permukaan material yang dilakukan menggunakan kotak besi tahan panas dengan penambahan karbon aktif.…”

“…This presented some difficulties when comparisons were made with the theoretical analysis of Smith [16], which predicted no effect of grain size, per se. The dilemma was resolved by a set of experiments [13] carried out to demonstrate that, in simplycooled mild steels, carbide thickness increased monotonically with grain size, so that the variation of σ F with 'grain size' was, in fact, a reflection of the variation of σ F with carbide thickness, 2c as predicted by equation (5.2). Further studies on spheroidal carbide distributions showed that σ F was related in a linear fashion to c −0.5 as predicted by equation (5.3), and that the 'effective work of fracture, γ p ', was approximately 8-14 Jm −2 .…”
