The p.ime objectiv. of the p.esent study is to exa.ine the effect of temp.ra. ture dep.ndent v.scosity/z（T） on the rev.lv.ng a.i-symmetric la.ina. bounda.y la.er flow of a. incomp.essible, electrica.ly non-conducting ferrofiuid in the p.esence of a.sta.iona.y p.a.e subjected to a.ma.netic field a.d ma.nta.ned a. a.uniform temp.ra.ure. To serv. this p.rp.se, the non-linea. coup.ed p.rtia. differentia. equa.ions a.e firstly conv.rted into the ordina.y differentia. equa.ions using well-known simila.ity tra.sforma.ions. The p.p.la. finite difference method is emp.oyed to discretize the non-linea. coup.ed differ- entia. equa.ions. These discretized equa.ions a.e then solv.d using the Newton method in Ma.La., for which a. initia. guess is ma.e with the help.of the Flex p.E Solv.r. a.ong with the v.locity p.ofiles, the effects of temp.ra.ure dep.ndent v.scosity a.e a.so exa.ined on the skin friction, the hea. tra.sfer, a.d the bounda.y la.er disp.a.ement thickness.

This unusua. beha.3}or of the mecha.ism of softening a.d the p.esence of the inv.rse stra.n ra.e dep.ndence of stra.n resista.ce ca. be exp.a.ned by blocking the motion of free disloca.ions by foreign a.oms, which occurs a. stra.n ra.es ra.ging between 0.06 a.d 0.1 s-1 This p.ocess results in disloca.ion p.le-up. thereby ca.sing in sire recrysta.liza.ion. a. stra.n ra.es exceeding 0.16 s-1, there is no intensiv. blocking of disloca.ions, lea.ing to a.direct stra.n ra.e dep.ndence of stra.n resista.ce.
