### GATE 2019 Syllabus for Metallurgical Engineering (ME)

GATE 2019  – In engineering/ technology/ architecture and P.hD, it is conducted to offer admission into M.Tech/M.Sc. GATE 2019 Mock Tests have been released, GATE 2019 exam is managed by the IIT. Graduate Aptitude Test in Engineering (GATE) is a national level examination and in relevant branches of science.

In each of the GATE 2019 subjects, the topics have been divided into two categories. On core topics, the corresponding sections (of the syllabus given below) of the question paper will contain 90% of their questions and the remaining 10% on Special Topics.

With the study of metals, metallurgical engineering is one of the branches of engineering that deals in which aspects of theoretical, practical, production, application of metals and their alloys are involved. The course explains about the mining, extraction, design, and processing of metals, as well as how metals react to environmental changes or stress.
