Metallographic analysis of welded joints of nickel alloy turbochargers

, 2016
Práce je zaměřena na metalografickou analýzu svarových spojů dvou různých turbín turbodmýchadel, vzniklých svařováním elektronovým paprskem. Lopatky první turbíny jsou vyrobeny z niklové super slitiny Inconel 713C a stopka z nízkolegované oceli 42CrMo4 ...

Two‐Stage Isothermal Transformation of Austenite into Nanobainite in a Chemically Inhomogeneous Medium‐Alloy Steel Containing 0.5 wt% C

steel research international, Volume 97, Issue 6, Page 3308-3327, June 2026.
The effect of chemical inhomogeneity on the microstructure and properties of nanobainitic steel is investigated. A two‐stage isothermal heat treatment that produced a more uniform microstructure is designed. The first‐stage temperature is higher than the MS of depleted bands; conversely, the second‐stage temperature is lower than the first‐stage ...

Microstructure Evolution in Directionally Solidified Fe–C–Mn–(Si) Peritectic Steels

steel research international, Volume 97, Issue 6, Page 3133-3142, June 2026.
This study investigates how growth velocity and silicon additions affect dendritic morphology, primary arm spacing, and mushy‐zone evolution in directionally solidified quaternary peritectic steels. Silicon substantially broadens the freezing range and lengthens the mushy zone, increasing susceptibility to interdendritic cracking.

Effect of Postweld Heat Treatment on Laser‐Welded Duplex Stainless Steel: Crystallographic Patterns and Fatigue Behavior

steel research international, Volume 97, Issue 6, Page 3267-3281, June 2026.
Laser welding of duplex stainless steel disrupts phase balance, promotes nitride precipitation, and reduces fatigue resistance. Postweld heat treatment restores austenite and dissolves nitrides, but the resulting crystallography and phase morphology still impair fatigue performance.
