This study explores the effects of ultrafast heating on AISI 304 austenitic stainless steel. The research shows that can lead to fine-grained mixed microstructures in steel, making it a potential alternative for modifying microstructure demonstrates minimum temperature 980 °C is required achieve fully recrystallized microstructure. results also suggest lower result finer grain size compared hig...

An Al/Stainless Steel/Al lamellar composite was produced by roll bonding of the starting sheets at 400 °C. Afterward, the roll bonded sheet was cut in half and the accumulative roll bonding (ARB) process at room temperature was applied seven times. As a result, the central steel layer fractured and distributed in the Al matrix among different layers introduced by the repetition of roll bonding ...

In this study, the hot deformation processing map of AISI 304 austenitic stainless steel in two initial grain sizes of 15 and 40 μm was investigated. For this purpose, cylindrical samples were used in the hot compression test at the temperature range of 950-1100 °C and the strain rate of 0.005-0.5% s-1. At first, the relationship between the peak stress and Zener-Hollomon parameter w...

Structural changes in Ti1-xAlxN coated tool inserts used for turning 316L stainless steel were investigated by XANES, EXAFS, EDS, and STEM. For coarse-grained fcc-structured coatings, with 0 ≤ x 0.62, the XANES spectrum Al-content. Ti 1s line-scans across rake face of worn samples reveals that TiN-enriched domains have formed during Ti0.47Al0.53N Ti0.38Al0.62N as a result spinodal decomposition...

I. Samardžić, Faculty of Mechanical Engineering Slavonski Brod, Croatia, A. Ćorić, Bratstvo, Novi Travnik, Bosnia and Herzegovina, M. Dunđer, Department for Polytechnic, University of Rijeka, Croatia. This paper presents the results of weldability investigation on welded joints made of fine grained high-strength S1100QL steel. The investigations are performed on two welded plates by HV 10 hardn...

The article presents results of comparative A-TIG welding tests involving selected unalloyed and fine-grained steels, as well high-strength steel WELDOX 1300 austenitic stainless AISI 304L. involved the use single ingredient activated fluxes (Cr2O3, TiO2, SiO2, Fe2O3, NaF, AlF3). In cases carbon low-alloy revealed that greatest increase in penetration depth was observed steels which had been de...
