In situ neutron diffraction studies of martensitic transformations in NiTi

, 2003
Martensitic transformations in commercial near equiatomic Ni49.5Ti (at. %) polycrystalline thick wires induced by thermal and/or mechanical loading were investigated by in-situ high-resolution neutron powder diffraction techniques with the aim to develop

Martensitic and related transformations in Ni-Al alloys

, 1995
: The present paper gives a review of results of recent studies investigating the fundamentals of the martensitic and related phase transformations in Ni-Al. For the former case, the emphasis will be on the microstructure of martensite plates. The latter

Nanoprecipitate characterisation in NiTi and aluminium alloys: A TEM‐based overview

Journal of Microscopy, EarlyView.
Abstract Nanoscale precipitates are central to the functional and mechanical performance of many advanced alloys, yet their characteristics and spatial distributions can be directly resolved only by electron microscopy. In this poster‐style article, focused ion beam‐prepared TEM lamellae are used to provide a microscopy‐focused overview of ...

Analysis of Corrosion and Wall Perforation in the Heat Exchanger Made of AISI 316L Stainless Steel

Materials and Corrosion, Volume 77, Issue 11, Page 1942-1955, November 2026.
Elevated passivation temperature is identified as the dominant factor triggering localized corrosion and subsequent perforation of AISI 316L heat exchanger tubes. Electrochemical and complementary characterization results show that the alloy retains high resistance to general, pitting, and intergranular corrosion, indicating that failure primarily ...
