Instructor bio

Prof. Jyotsna Dutta Majumdar

IIT Kharagpur

Prof. Jyotsna Dutta Majumdar is serving for the Department ofMetallurgical and Materials Engineering, Indian Institute ofTechnology Kharagpur as Professor. Her areas of specializationinclude the following: (a) surface engineering, (b) surface modification and coating technology, (c) advanced materials processing and (d) corrosion and environmental degradation. She is well known internationally for her research contribution in the field of Metallurgical and Material Engineering with focus on surface engineering and laser surface processing. She made fundamental contributions to a profound understanding of the metallurgy of rapid solidification of metals under the specific heat input of a laser source. Her works also concern a detailed structure-property correlation of laser surface modified metallic materials with a specific goal to improve certain engineering properties. She also stated a brief understanding of the mechanism of wear, corrosion and high temperature oxidation of the metastable microstructures developed in commercial metals and alloys due to laser processing. Extensive efforts were also made for the first time for the development of compositionally graded surface and nano-dispersed surface for thermal barrier and hot corrosion application by application of hybrid coating technology.
