d. Strength of a glass piece can be enhanced by:

A. precipitation hardening

B. annealing

C. reducing the average grain size

D. tempering

E. cold working

e. An eutectic alloy is characterized by

A. lenticular particles in a solid phase

D. a concentration ingredient

Solutions

Expert Solution

Ans A : A) Young`s Modulus and C) Yield Strength ,It has two right answers to it that is, it is the best indicator of the material resistance to the plastic deformation along with young`s modulus as well .

Ans B : A) Tempering and C) Strain Hardening ,It also has two right answers for this that is, Martensite steel is brittle due to the method of strain hardening and Tempering

Ans C : A) an interstitial oxygen for every two Na+ , you have to remove every two Na+ with oxygen placed at an interstital point in the crystal lattice .

Ans D : D) Tempering , it is used to enhance the strength of a glass piece . In this the piece of a glass is being heated at controlled temperature which makes the glass four times more than stronger .

Ans E : B) alternating layers of two phases , This is being done for with the mixture of metals having melting point lower than their components .

HOPE SO YOU WOULD APPRECIATE MY EFFORTS , PLEASE PROVIDE POSITIVE RATINGS . THANKYOU :)
