Can anyone help??

Match the following (Notice that there is one line on each column that does not have a match): (1) p-n junctions Cracking due to thermal and internal stresses Pearlite formation Reduces the magnitude of the Elastic Modulus Martensite Obeys Avrami Equation Optimum creep properties Deformation rate is temperature dependent Ceramic porosity Crystalline polymers Amorphous structures Continuous increase through cold working Thermal Shock Single crystals High T. creep semiconductors used to produce n-type extrinsic Si- Group V elements Used as current rectifiers high density thermoplastics Exhibit viscous flow above T_g

Explanation / Answer

Ans 1

p-n juctions ---- single crystals.

Ans 2

Pearllite is a two phased structure , lamellar in nature, consists of ferrite and cementite.

Ans 3

Martensite ------ cracking sue to thermal and internal stress.

Ans 4

Optimum creep properties ---- obeys Avrami equations.

Please note: The question paper contains 10 questions. 4 are fully answered. Here are 2 more hints.

Ans 5

Ceramic-porosity --- reduces the magnitude of elastic modulus.

Ans 10:

High density thermo plastics --------- Crystalline polymers
