Briefly describe the simplest heat treatment procedure that would be used in converting a 0.76 wt% c steel from one microstructure to the other, as follows:

(a) martensite to spheroidite

(b) spheroidite to martensite

(c) bainite to pearlite

(d) pearlite to bainite

(e) spheroidite to pearlite

(f) pearlite to spheroidite

(g) tempered martensite to martensite

(h) bainite to spheroidite

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
