ABSTRACT: The melt from the ladle wa-, poured through an interiTic(fi.j14-

temperature amounted to 600 , which caused considerable diffi-
culties in casting. It is established that the H content decreased
by 40-60 percent in the process of casting frorn the intermediate
ladle, whereas no changes were observed in Nl, the content of
0, and N, nor was any improvement observed in the mechanical
properties of the metal.

PURPOSE: This book is intended for engineers and technicians at Industrial
plantt,,for scientific personnel at research and educational institutions,
and for students of advanced metallurgy.
COVERAGEj The articles In this collection deal with the production.and hot
formihg of steel and titanium ingots. Both theoretical and practical
aspects are covered. Topics discussed includes crack formation during
thermomechanical treatment, dependence of plasticity of low-carbon chrome-
nickel steel on the method of steelmaking, vacuum melting of dustenitic
stainless stee!p beneficial effect of hot deformation on steel properties,
vectorial properties of sheet metal as related to rolling conditions,
crystallization and ingot structure, present status of titanium-ingot
production, etc. Numarous references, principally Soviet, accompany
the articles.

TITLE: On the Estimation of the Plasticity of Alloyed Low-Carbon
Steels According to the "ethod of Hot Settling (Ob otsenke
plastichnosti nlZkaugleroLstoy let~irovannoy stali po metodu

PERIODICAL: Zavodskayn Laboratorya, 1958, Vol. 24, Nr 7,
PP, 855 - 858 (USSR)
ABSTRACT: Methods exist for the estimation of the plasticity of steels
within the temperature range of hot deformation. In the present
paper the chromium-nic'-el steel of the tyf 221di2tBM is inves-
tigated within the range of forging temperatures, with the
cyl indri cal. sampl. es being somewhat mod if i ed; - thus three ex-
perimental series are obtained. The samples were heated to
900 - 12500 and t.,icre they were maintained for 40-60 minutes;
the crusher was settled with 700 tons with the settling degrete
amounting to 7Z- It was observed that the sample type with
four longitudinal grooves on the cylindrical face offered the
Card 1/2 best possibility of determination. This suggestion had been

made by S.I.Sakhin, I. T.Baruzdin and T.G.Barinov. In order
to be able to classify the influence exerted by other elements
0,09-,46 of titanium was added to the oteel (amonC others)
, . Tle
number of the cracks formed at the sample served as index of
the plasticity; the res-alts were represented graphically. It
may be seen that the cracks are f-.1--ed at 1075 - 11000, with
the addition of titanium not decreasing the range of cracks.
Based on the results obtained the authors az;zume that the
formation of cracks of the steel type mentioned above takes
Place at 1050 - 10800, whereas it was observed that an increase
of the carbon content decreases the brittleness, and a decrease
of the nickel content on certain conditions may cause an
improveatent of the deformability. The investigations carried
out at castinE~ temperatures between 1540 and 16700 were made
by S.I.Sakhin and T.G.Barinov. They showed that by increasing
the casting temperature the ranee of brittleness is extended by
500 on the plasticity curve towards higher temperatures; the
latter agrses with the observations made in production. There
-ro A figures, 2 tables, and 8 references, 7 of which are Soviet.

Investigations were made or the spectral radiating power of the
surface of metal baths or various chemical compositions using
various methods. Results mom in agreement. The regularities
established determined the connect-on between color temperature
and actual temperature of clean and oxidized metal-bath sur-

established that the value of the coefficient or transition
