However, our laboratory has developed alloys that, contrary to shape memory alloys, deform more and more when heated. This phenomenon can be applied to the manufacture of high-strength, thin-walled tubes, which has been difficult. We are also developing materials with opposite coefficients of thermal expansion, which shrink when heated and expand when cooled, and novel alloys that allow bimetallic motion with a single type of alloy.<\/p>\n<table class=\"el_table_fix\" style=\"width: 100%\">\n<tbody>\n<tr>\n<th style=\"width: 20%\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium\" src=\"https:\/\/www.elst.okayama-u.ac.jp\/up_load_files\/areas\/areas01_advmech\/TAKEMOTO Yoshito.jpg\" width=\"320\" height=\"408\"><\/th>\n<td style=\"width: 80%\">\n<ul>\n<li style=\"list-style-type: none;font-size: 12px;margin-left: -20px\"><span style=\"font-size: 12pt\">Asst.
