After the holding time, the mold was cooled down to a demolding temperature of 85[degrees]C.
The as-welded plates were isothermally heat treated in two steps; first the welded plates were austenitized at 900 [degrees]C for 2 hour holding time. After that they were immediately transferred to salt bath fixed at 300 [degrees]C and 350 [degrees]C and were kept in salt bath for 1.5 hour, 2 hour and 2.5 hour holding time.
0.3 grams of grey kaolin with a particle size of 250-350 [micro]m was subjected to a temperature of 400[degrees]C, under a nitrogen flow of 15ml/min, at different holding times (6, 12, 18, and 24 h) before starting the MBOH catalytic reaction.
[23] generate the holding time [D.sub.n,s] as a linear function of the schedule deviation of all buses at stop s:
Hence the size of the Ti[B.sub.2] particles, 2.5 to 3 [micro]m as observed for 810[degrees]C and 30 minutes holding time at location--1 is very much higher than the size of Ti[B.sub.2] particles, 1.0 to 1.5 [micro]m as observed for 750 oc and 10 minutes holding time and for the combination other pouring temperatures and holding times the size of Ti[B.sub.2] particles of location--1 are in between.[20-22] The location--1 was selected for analyzing the size of Ti[B.sub.2] particles as it is the top most point in the ingot and at this location the height of falling of liquid metal during pouring will be minimum at this location.
In fact, the activation energy is very sensitive to the sintering conditions such as the preparing procedure of green compacts, the sintering procedure, applied pressure, peak temperature, and its holding time, even for the same material.
The furnace temperature was set to 950[degrees]C, and after different holding time, the pressure of 30 MPa was applied.
Providing there are N work-pieces that their weight, holding temperature and holding time are given.
Nevertheless, it is necessary to optimize the combination of pulse holding time, the number of pulses and pressure levels in order to reach the desirable log-reduction of microorganisms compatible with the specific application at hand.
The austenitization temperature was 1050[degrees]C with 5s holding time. In the temperature interval between 950-720[degrees]C deformations consisting of four, eight and twelve steps took place (Tab.
The NSG 437 ESD Simulator meets the holding time of at least 5 s required by the global ESD standards.
After a certain holding time the magnet is switched off and the stored neutrons fall into the detector.
