The results show that the most important impact parameter on the HIP process is temperature, followed by pressure and time. The tensile strength, yield strength, elongation, Brinell hardness, axial fatigue life and Q value of ZL114A alloy within the micro-porosity of grade III are increased to 340 MPa, 280 MPa, 8%, 125HBS, 4.1×10⁵ and 475.45, respectively after the HIP process under 540℃, 140 MPa and 4 h conditions. Cconsidering both the process cost and effect, the optimal parameters of HIP process are 540℃, 140 MPa and 2 h. Compared with the micro-porosity of grade III, the Q values of grade I and grade II are increased by 5.1% and 2.4%, respectively after the HIP process, whereas the Q values of grades IV and V are decreased by 15.98% and 25.61%, respectively., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null, pdf=a7fqxM81wqSlh6r8mPG1rQ==, pdfFileSize=2872475, pdfExtLink=null, richHtmlUrl=null, mobilePdfUrl=null, reviewReport=null, pdfFirstPage=null, abstractGraph=null, abstractGraphContent=null, abstractVideo=null, citation=null, cebUrl=null, magXmlContent=null, mapNumber=null, authorCompany=1.
