Heat affected zone microstructures and their influence on toughness in two microalloyed HSLA steels
Microstructures and Charpy impact properties have been examined in two microalloyed steels following heat treatments to simulate weld heat affected zone (HAZ) structures over a range of heat input conditions, characterised by the cooling time from 800 to 500 !C (Dt8/5). The base materials were low carbon structural steel plates microalloyed with vanadium and nitrogen (V–N) and niobium (Nb), res...
متن کاملthe effects of keyword and context methods on pronunciation and receptive/ productive vocabulary of low-intermediate iranian efl learners: short-term and long-term memory in focus
از گذشته تا کنون، تحقیقات بسیاری صورت گرفته است که همگی به گونه ای بر مثمر ثمر بودن استفاده از استراتژی های یادگیری لغت در یک زبان بیگانه اذعان داشته اند. این تحقیق به بررسی تاثیر دو روش مختلف آموزش واژگان انگلیسی (کلیدی و بافتی) بر تلفظ و دانش لغوی فراگیران ایرانی زیر متوسط زبان انگلیسی و بر ماندگاری آن در حافظه می پردازد. به این منظور، تعداد شصت نفر از زبان آموزان ایرانی هشت تا چهارده ساله با...
15 صفحه اولLow–carbon Steels: the Calculation of Mixed–microstructures & Their Mechanical Properties
Steels are being designed with ever decreasing interstitial contents. At the same time, processing technology allows accelerated cooling without excessive distortion or microstructural gradients [1–5]. Lean steels with lower ‘carbon equivalents’ can therefore be manufactured, making fabrication relatively easy. Alloys such as these give uniform microstructures in spite of solidfication–induced ...
متن کاملPanel Discussion on: Recovering Low Energy Physics
Continuation of the discussion on semi-classical issues from two weeks ago following John Barret's talk. Main Issue that came up two weeks ago: • In semi-classical considerations: 1) is it adequate to focus on states represented by just a few simplices with faces which have large areas (i.e., dual graphs whose edges have large j values); or, 2) Must we consider states with lots of edges with lo...
متن کاملStructure and properties of TM processed HSLA steels
This paper deals with the influence of steel composition (with respect to the microalloying elements) and therrnomechanical treatment on structure and mechanical behaviour of HSLA (High Strength Low Alloy) steels. Four different microalloyed steels have been TM rolled under variing conditions. The austenite structure prior to transformation could be revealed by means of a special etching techni...
