Dendritic growth in the carbon tetrabromide and hexachlorethane system

Dependency of the dendritic arm spacings and tip radius on the growth rate and composition in the directionally solidified succinonitrile–carbon tetrabromide alloys

“…[15]. The exponent values of l 1 ; l 2 and R for SCN-CTB alloys obtained in the present work are in good agreement with the exponent values of l 1 ; l 2 and R obtained in previous works [15][16][17][18][19][51][52][53][54][55]57,58].…”

“…As can be seen from Table 3, the average value of l 2 =R obtained in present work for SCN-CTB alloys is in good agreement with the value of l 2 =R estimated by Langer and Mu¨ller-Krumbhaar [26]. A comparison of l 2 =R values obtained in present work with the previous experimental works [16,17,19,37,47,54,55,[66][67][68][69] is also given in Table 3. The average value of l 2 =R for SCN-CTB alloys obtained in present work is in good agreement with values of l 2 =R for different alloys obtained by previous workers.…”

“…The goal of the present work was to experimentally investigate the dependency of the l 1 ; l 2 and R on V and C 0 in the directionally solidified succinonitrile (SCN)-carbon tetrabromide (CTB) binary eutectic system and to compare the results with the current theoretical models [23,26,[32][33][34][35][36][37] and previous experimental results [6,[15][16][17][41][42][43][44][45][46][47][48][49][50][51][52][53][54][55]. In present work, the secondary dendrite arm spacings have additionally been measured and the range of the compositions was increased up to 40 wt%.…”

Effects of growth rate and temperature gradient on the microstructure parameters in the directionally solidified succinonitrile–7.5wt.% carbon tetrabromide alloy

“…Available experimental results related to the values of 1 , 2 , R and (d) can be found in Table 2. As can be seen from Tables 1a, 1b and 2, the exponent values of Huang and Glicksman (1981) alloy with a constant growth rate at different temperature gradients and with a constant temperature gradient at different growth rates obtained in the present work are in good agreement with the exponent values of 1 , 2 , R and (d) for the same alloys and different organic materials obtained by previous workers (Ç adırlı et al, 1999Kaya et al, 2005;Üstün et al, 2006;Taha, 1979;Grugel and Zhou, 1989;Dey and Sekhar, 1993;Kirkaldy, 1993, 1994b;Seetharaman et al, 1989;Trivedi and Mason, 1991;Tiller et al, 1953;Kurz and Fisher, 1989;Esaka and Kurz, 1985;Cattaneo et al, 1994;Billia and Trivedi, 1993;Shangguan, 1988;Ma, 2002Ma, , 2004Trivedi et al, 2003;Gorbunov, 1992;Glicksman, 1984;Honjo and Sawada, 1982;Liu et al, 2002;Hansen et al, 2002;Huang and Glicksman, 1981).…”

“…The aim of present work is to experimentally investigate the effect of the temperature gradient and growth rate on the microstructure parameters in the directionally solidified SCN-7.5 wt.% CTB alloy and to compare the results with theoretical models (Lu and Hunt, 1996;Langer and Müller-Krumbhaar, 1978;Hunt, 1979;Kurz and Fisher, 1981;Bouchard andKirkaldy, 1996, 1997;Trivedi and Somboonsuk, 1984) and previous experimental results (Han and Trivedi, 1994;Ç adırlı et al, 1999Kaya et al, 2005;Üstün et al, 2006;Mullins and Sekarka, 1965;Glicksman and Singh, 1986;Schmidbauer et al, 1993;De Cheveigne et al, 1985;Huang et al, 1993;Taha, 1979;Grugel and Zhou, 1989;Dey and Sekhar, 1993;Liu and Kirkaldy, 1994a;Seetharaman et al, 1989;Trivedi and Mason, 1991;Tiller et al, 1953;Kurz and Fisher, 1989;Esaka and Kurz, 1985).…”
