  3. IES - 2006 What does hydrostatic pressure in extrusion process improve? (a) Ductility (c) Brittleness (b) Compressive strength (d) Tensile strength


  4. GATE-1990 (PI) Semi brittle materials can be extruded by (a) Impact extrusion (b) Closed cavity extrusion (c) Hydrostatic extrusion (d) Backward extrusion


  5. IES - 2001 Which of the following statements are the salient features of hydrostatic extrusion? 1. It is suitable for soft and ductile materia 2. It is suitable for high-strength super-alloys. 3.The billet is inserted into the extrusion chamber and pressure is applied by a ram to extrude the billet through the die. 4. The billet is inserted into the extrusion chamber where it is surrounded by a suitable liquid. The billet is extruded through the die by applying pressure to the liquid. Select the correct answer using the codes given below: Codes: (a) 1 and 3 (b) 1 and 4 (c) 2 and 3 (d) 2 and 4


  6. For IES Only IES 2014 Statement-l: For high extrusion pressure, the initial temperature of billet should be high. Statement-l: As the speed of hot extrusion is increased, it may lead to melting of alloy constituents (a) Both Statement (1) and Statement (Il) are individually true and Statement (II) is the correct explanation of Statement (I) (b) Both Statement (I) and Statement (II) are individually true but Statement (II) is not the correct explanation of Statement (c) Statement (I) is true but Statement (II) is false (d) Statement (I) is false but Statement (Il) is true


  7. JWM 2010 Assertion (A) : Extrusion speed depends on work material. Reason (R) High extrusion speed causes cracks in the material. (a)Both A and R are individually true and R is the correct explanation of A (b)Both A and R are individually true but R is not the correct explanation of A (c) A is true but R is false (d)A is false but R is true
