please answer for all questions in advance

Answer 1

Observe the 109) The micro structure of cast iron depends upon the composition of chemical substances, and also the temperature. We from the image it is pearline ferritic cast iron present there eutectie cells contains ferrite always. in cast iron is mostly also known as grey iron or white iron. li) It has a flane type structure. (ill) There i's a ferrite pearlite substance in it. (V) The micro structeine contains rane hipei Aarne size cast iron 1 (b) crystallization characteristics of ane ii) The modification done in the production of cast iron 1S done by the sphenoidizers which has a high boiling point promotes the evolution of hydrogen from the liquid cast iron (ii) The evolution of gases from Liquid cast iron promotes me homogenization of cast iron at modification temperature is done in all methods of obtaining Spheroidal graphite. in During the melting of anmodified cast iron, an interaction take place will 1.10) Application of these cast iron are is manufacturing pipes livo automobile paris (i) anchor of ships. (Ul machine manufacturer (if making utensils

2 (8) and are al Nodular cast iron. The cast iron present here Pherordal graphite in dark coloured so.it is Nodular Spheroidal graphire cast iron, Nodul on iron also called ductile iron. i) The graphite is present af tiny balls or spheroids tü ? Because of me spheroide interrupt the matrix much less than graphite Makes, nodular cast iron than has higher strength toughnes gray cast iron, (b) crystallization characteristics of these tipe cast iron follows. In placing of master alloys wing bells made of different materials, 1) making a pure magnesium in a converter ladie. making magnesium in the carrier gas steam through a po rolul stopper located at me bo tom of the ladle, wire treatment and making my into the ladle placed in the autoclave (L): Applications are is making hubs and structural part in wind power Lit2 m iN) cored inaustry. (ily high tension piano strings, (iv) Grade by En standard EN-G IS-400-15EN - GTS-400-18.
