Abstract
THE recent publication by Petch and Stables1 dealing with the delayed fracture of metals under static load has been read with interest. Work of a similar nature, to investigate the liability of an alloy steel to crack in the heat-affected zone when it is metal-arc welded under certain conditions, has been in progress in the laboratories of the British Welding Research Association since December 1951.
