Role of strain-induced martensite on microstructural evolution during annealing of metastable austenitic stainless steel
Metastable austenitic stainless steel of type AISI 304L was cold rolled to 90% with and without inter-pass cooling. Inter-pass cooling produced 89% of strain-induced martensite whereas no inter-pass cooling re...

Choice of the Striking Point in the Pianoforte
THE experiments dealing with the amplitudes of the partials from a struck string are many, and the conclusions are varied. For example, the experiments of W. H. George (Phil. Mag., vol. 50, August 1925) show maxi...
