As the J dominance regime is reached, the initial J-integral values, J(i), are definite even if the elastic component Ji(e) and plastic component Ji(p)vary with the thinkness of specimen. The wider the specimen width, the larger the Ji(e)/Ji and the smaller the Ji(p)/Ji. The crack propagation resistance, dJR/da and dJp/da, decreases, while dJe/da increases linearly with increasing specimen thinness.Based on the above experimental results, an empirical formula dJ/da = α+β. B is given, which can be used to evaluate the safety of practical structural components.A modified J-integral is presented, upon which a new view is Put forward that the increase in crack  growth resistance is induced mainly by the increase in the plastic J-integral component with the crack propagation,","authors":[{"authorName":"H.P.

Spin-reorientation transitions were observed in RFe11Ti with <span style=\"color:red\">R</span>=Nd (<span style=\"color:red\">T</span>(SR)=189 K), Tb (<span style=\"color:red\">T</span>(SR)=339 K), Dy (<span style=\"color:red\">T</span>(SR1)=214 K and <span style=\"color:red\">T</span>(SR2)=98 K), and Er (<span style=\"color:red\">T</span>(SR)=48 K). First-order magnetization processes of type I for <span style=\"color:red\">R</span>=Nd and Er and of type II for <span style=\"color:red\">R</span>=Ho and Tm were detected at low temperatures. The uniaxial magnetocrystalline anisotropy fields of the whole RFe11Ti series have been determined in a wide temperature interval from 4.2 K to the Curie temperatures. It is deduced that the ''anomalous increase'' in the magnetization <span style=\"color:red\">curve</span> of SmFe11Ti for the external field perpendicular to the c axis is not a first-order magnetization process, but a continuous rotation of the magnetic moment under the action of the external field. The observed magnetic phase transitions, the spin-reorientation transitions, and the first-order magnetization processes in the RFe11Ti compounds are well described in terms of a crystal-field description in which the rare-earth sublattice (<span style=\"color:red\">R</span>) and transition-metal sublattice (<span style=\"color:red\">T</span>) exchange interaction is included. A set of crystalline-electric-field parameters as well as the values for the <span style=\"color:red\">R-T</span> exchange field are deduced for the whole RFe11Ti series from fitting the experimentally obtained values of the anisotropy field, the critical field for the first-order magnetization process, and the spin-reorientation temperature with the calculations in the present systematic <span style=\"color:red\">study</span>. Magnetic anomalies are observed in the temperature dependence of the ac susceptibility of the RFe11Ti compounds with <span style=\"color:red\">R</span>=Nd, Sm, Er, and Tm. They are shown to be connected with domain-wall motion.","authors":[],"categoryName":"|","doi":"","fpage":"3231","id":"a323912d-b81e-412c-b036-cb5a8a4e8ab3","issue":"6","journal":{"abbrevTitle":"PRB","id":"41d73232-e732-4216-a5f7-4b352bb955cf","issnPpub":"0163-1829","publisherId":"PRB","title":"Physical Review B"},"keywords":[{"id":"364f9336-3c2a-4c5e-9f47-2632c423f9a8","keyword":"spin-reorientation;single-crystal;intermetallic compounds;fe;ti;nd2fe14b;susceptibility;exchange;systems;<span style=\"color:red\">curve</span>","originalKeyword":"spin-reorientation;single-crystal;intermetallic compounds;fe;ti;nd2fe14b;susceptibility;exchange;systems;curve"}],"language":"en","publisherId":"0163-1829_1993_6_1","title":"MAGNETIC PHASE-TRANSITIONS, MAGNETOCRYSTALLINE ANISOTROPY, AND CRYSTAL-FIELD INTERACTIONS IN THE RFE11TI SERIES (WHERE <span style=\"color:red\">R</span> = Y, PR, ND, SM, GD, TB, DY, HO, ER, OR TM)","volume":"47","year":"1993"}],"totalpage":1749,"totalrecord":17482}
