  5. 4. A critical survey of the grain refining mechanisms of aluminium

    Författare :Mats Johnsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; strukturkemi; Structural Chemistry;

    Sammanfattning : In the present work, several possible interpretations of the grain refining mechanisms of aluminium castings after additions of titanium and boron are compared with the results of critical test experiments. The presence of B does not seem to affect the binary Al-Ti phase diagram close to the A1 comer, except for formation of boride phase. LÄS MER

  7. 5. On the Nucleation and Inoculation of Metals

    Författare :Lena Magnusson; Hasse Fredriksson; Peter Schumacher; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solidification; nucleation; inoculation; undercooling; interface energy; refractory metals; latent heat; inclusions; nodular cast iron; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Latent heat during recalesence and nucleation and post-recalesence temperature was analysed for refractory metals. An effect on latent heat was found by alloying the pure elements with other refractories. Latent heat was found to be 15-65% of tabulated values. Interface energy was evaluated from undercooling experiments. LÄS MER
