A mrchanisnl is described for the formation of whiskers on a crystal which is growing by vapor deposition.

A necessary condition is the existence of diffusion-limited transfer of material or heat,. The mechanism is supported by Brenner's observations that metal whiskers formed hy vapor-phasr reduction illvariably grow from previously deposited material. lMl%ANISME DE CROISSANCE DES BARBES-III NATURE DES SITES DE CKOISSANCE Un m&anisme est d&it pour la formation des harbes sur un cristal qui grossit par dBp6t de vapeur. me condit,ion &cessaire est l'existence d'un transport limit6 par diffusion de mat,i&re ou de chaleur. 1,e m&canismr est appuyk par les observations de Brenner, d'apr&s lesquelles des barbes de metaux form& par r&dnction de la phase x-apeur, grossissent ind&prndamment de la mat,ibre pr&tlablcrncnt tlPpos&. MECHASISMLX DES WHISKER-WACHSTUMS-III NATUR DER W,4CHSTUMSSTELLES Es wird ein Mechanismus fiir die Bildung van "Whisker" auf einem aus der Dampfphase wachsenden Kristall beschriehen. Eine notwendige Bedingung ist dabei das Vorhandensein eines durch Diffusion begrenzten Material-oder Wgrmeiibergangs. Der Mechanismus wird durch die Beobachtungen van Brcmner gestiitzt, nach denen durch Reduktion aus der Dampfphase gehildetc Metall-Whisker ohrw _4usnahme aus dem x-orher abgeschiedenen Material heraus wachsen.
