For　the　riveting　of　a　titanium　alloy　rivet　with　high　strain　rate　sensitivity,　effects　of　a　loading　rate　on　TA1　rivet　deformation,　energy　efficiency,　and　the　riveting　joints　between　TA1　rivet　and　steel　plate,　TA1　rivet　and　laminates　of　a　composite-steel　sheet　in　electromagnetic　riveting　(EMR)　were　investigated　through　experiments　and　microstructure　analysis.　The　results　show　that　TA1　riveting　can　be　carried　out　by　two　kinds　of　loading　rates　with　different　magnitudes.　The　increasing　loading　rate　contributes　to　more　remarkable　deformation　in　the　adiathermal　shear　zone.　With　an　appropriate　loading　rate,　a　good　riveting　joint　can　be　obtained　between　the　TA1　rivet　and　laminates　of　the　composite-steel　sheet.　The　low　loading　rate　of　the　EMR　process　enables　the　transfer　of　heat　generated　during　the　rivet　deformation,　the　postponing　of　cracks,　a　fine　grain　in　the　region　of　rivet　deformation,　and　the　enhancement　of　the　deformation　limit　of　the　rivets.
