Three-dimensional nonlinear thermal and thermo-mechanical numerical simulations are conducted for the friction stir welding (FSW) of 304L stainless steel. The finite element analysis code—WELDSIM, developed by the authors specifically for welding simulation, was used. Two welding cases with tool rotational speeds of 300 and 500 rpm are analyzed. The objective is to study the variation of transi...

Austenitic Type 304L stainless steel (SS) and martensitic Alloy EP-823 have been identified as candidate structural materials to contain spallation arget for transmutation of nuclear waste. Welded specimens consisting of either or both materials have been evaluated by transmission electron icroscopy (TEM) to determine the dislocation density near the heat-affected-zone (HAZ) and the base materi...

Abstract The objective of the work is to present a new approach simulation thermal field in laser beam welding, based on an experimentally-fitted analytical model, applied investigate weldability AISI 304L austenitic steel. Reference made welding trial single pass two 10 mm thick butt-positioned plates. Welding was performed under keyhole full penetration mode, which characteristic high-power b...

The knowledge of alloy–process–structure–property relationships is particular interest for several safety-critical brazed components and requires a detailed characterization. Thus, three different nickel-based brazing filler metals were produced with varying chromium molybdenum content used to braze butt joints the austenitic stainless steel AISI 304L under vacuum. Two holding times evaluate di...

The Attachment Insecurity Screening Inventory (AISI) 2-5 years is a parent-report questionnaire for assessing attachment insecurity in preschoolers. Validity and reliability of the AISI 2-5 years were examined in a general sample (n = 429) and in a clinical sample (n = 71). Confirmatory factor analysis (CFA) confirmed a three-factor model of avoidant, ambivalent/resistant and disorganized attac...
