Surface Nanocrystallization of Stainless Steel with ZAF Method and SEM Technique
نویسندگان
چکیده
From a nano electronic circuit designer’s point of view the growth of ultrathin film in the ultra high vacuum chamber (UHVC) would imply better stainless steel structure. ZAF method and SEM (scanning Electron Microscopy) technique are used to realize surface nano crystallizafion on an stailness steel sample. The as-welded condition of UHVC is also studied to see if this chamber can prevent weld "hot cracking". The aim is to find a way to synthesis a good and uniform content elements of stainless steel . UHVC with iron-based alloys containing a minimum of 10 percent chromium (Cr) with 20 percent Ni , Mn and Si can keep UHV conditions down to 10 10 Torr. 15 18

Ion implantation is a surface modification technology to produce new material on the surface by impingement of high energy ions from the ion accelerator. In this work, AISI 304 stainless steels were coated with 90 nm Ni film by electron beam deposition and implanted by a flow of 5×1017 N cm−2 at 400 K temperature with different implantation energies of 10, 20, 30 and 40 keV. The prepared sample...
متن کاملFatigue behavior of Austenitic Type 316L Stainless Steel
The aim of this work is to determine the fatigue life of 316L stainless steel. The mechanisms of fatigue of 316L stainless steels were investigated and discussed. The fatigue tests were carried out at constant-amplitude cyclic loading with load ratio R=0.1. Scanning Electron Microscope (SEM) is then used to examine the fracture surface. The results show that the fatigue limit of 316L stainless ...
