    Hi friends...
     
    this is a paper for Metallurgy & Material Science Engg conducted by the HAL Engine Division at Koraput on the 15th of Feb 2009 held at Bhubaneswar.It was a paper for 1.5 hrs duration and consisted of 100 qns. The qns were relatively simple though I did not crack it ...Here they concentrated more on Physical Metallurgy,NDT Methods and Mechanical Metallurgy. There were a few qns on XRay Metallography too...here are a few qns as far as my memory goes...hope u like them!
    1.  The faster the ncooling the interdendritic spacing will be > less,>more,>same.
    2. Definitions of Toughness,Resilience,Hardness,Youngs' Modulus.
    3.  The material that is the lowest on the Mohs' scale is _______
    4.  The composition of Constantan is _______
    5.  The effect not observed in a Thermocouple is  Raman Effect.
    6.  Permalloys are used in making ______ kind of magnetic materials.
    7.  Which property of the pigment is used in NDT Methods 
    8. Mond's process is used in the extraction of ____________.
    9. The gas blown during the LD Process of Steel Making is ______________.
    10. Intricate parts are manufactured by a> Casting b> Welding c> Forging d> Rolling
    11.  In case carburising the depth of penetration is proportional to sqrt(t).
     
    Well this is how much I can remember ....dont waste ur time on learning Extractive Metallurgy and other things...concentrate on Physical Metallurgy by Avner and Mechanical Metallurgy by Dieter...
