Testing of Microalloyed Steel Quality under Creep Conditions for a New Intended Use
Advances in Materials Science and Engineering, 2017 The paper deals with the testing of microalloyed steels H300LAD and H380LAD under creep conditions. To test the properties of these steels, tensile and creep tests were carried out in the temperature range of 200–500°C.

Effect of the morphology of the martensite-austenite phase on fracture of the weld heat affected zone in vanadium and niobium microalloyed steels [PDF]
, 2010 In multipass welding, the intercritically reheated coarse grained heat affected zone demonstrates the worst toughness in welded joint, since it contains a high-carbon martensite with some retained austenite, known as M-A phase, which is brittle and ...
