The ATLAS experiment has an extensive research program focusing on various aspects of heavy flavor decays.
Operating LHC experiments at a center-of-mass energy $\sqrt{s}= 13~\mathrm{TeV}$ opens new opportunities to measure the properties of the $B$ hadrons precisely.
The first part of this paper focuses on the most recent measurement of the $B_c^+$ rare decay, which is reconstructed in the $B_c^+\to J/\psi D_s^{(*)+}$ decay channel.
The second part of this paper presents an overview of b-hadron measurements performed by the ATLAS experiment involving lifetime parameters.
