WAXD INVESTIGATION OF THE SECOND ORDER RESIDUAL STRESS INTO THREE HIGH ALLOYED STEELS
Journal Title: Journal of Science And Arts - Year 2009, Vol 11, Issue 2
Abstract
Mechanical processing like milling, polishing, grinding, etc generate internal residual stresses of the first order (macrostresses) at bulk level and of the second order (σ11) at the crystallite level. The paper addresses the σ11 depth profiles induced by milling and mechanical polishing in three high alloyed steel grades of AISI 316 types. These grades are used for implants manufacture. The σ11 depth profiles were used to select the proper mechanical regime related to steel grade in order to minimize cracks initiation and/or cracks propagation. These researches take part from a large project aimed to improve metallic implant manufacture technology.
